TECHNICAL FIELD

The technical field relates generally to a process for producingproducts for keratin fibers, and more particularly relates to a processfor producing a colorant for keratin fibers.

BACKGROUND

Human hair is treated nowadays with cosmetic hair preparations in manyways. These include, for example, cleaning the hair with shampoos, careand regeneration using rinses and therapies, and bleaching, coloring,and reshaping the hair using coloring agents, toning agents, wavingagents, and styling preparations. Agents for modifying or tinting thecolor of head hair play a predominant role in this context.

For temporary coloring, it usual to use coloring or toning agents thatcontain so-called substantive dyes as a coloring component. These aredye molecules that absorb directly onto the substrate and do not requirean oxidizing process in order to form the color. Included among thesedyes are, for example, henna, which has been known since antiquity forcoloring the body and hair. These color results are, as a result, muchmore sensitive to shampooing than are the oxidation-based colors, sothat a (very often undesirable) shift in tint, or even a visible loss ofcolor, then occurs much more quickly.

So-called oxidizing coloring agents are used for permanent, intensecoloring results with corresponding fastness properties. Such coloringagents usually contain oxidation dye precursors, so-called developercomponents and coupler components. The developer components, under theinfluence of oxidizing agents or atmospheric oxygen, form among oneanother, or by coupling with one or more coupler components, the actualdyes. The oxidizing coloring agents are notable for outstanding,long-lasting color results. For natural-looking coloring results, it isusually necessary to use a mixture of a larger number of oxidation dyeprecursors; in many cases, substantive dyes are also used for toning.

These coloring agents, in particular oxidizing coloring agents orhair-bleaching powders, are as a rule manufactured by manually mixingprefabricated active-substance compositions, for example two oxidizingcoloring agents or two bleaching agents. Manual intermixing is, however,time- and labor-intensive; for example, the constituents need to beweighed out before mixing. In addition, homogenization of the mixture bymanual mixing of the active substances is time-intensive. The user isfurthermore exposed to dust that may occur when processing solidactive-substance compositions.

In light of this, US patent application 2005/0169871 A1 (L'Oreal)describes a method for manufacturing active-substance mixtures for hairtreatment, in which method a liquid is directed, at elevated temperatureand at a pressure above 3 bar, through a polymer-containing preparation.Although this method is suitable for manufacturing a mixture of theactive substances being used, the mixture obtained nevertheless, becauseof its inhomogeneity and insufficient viscosity, leaves room forimprovement especially for utilization in hair coloring.

Accordingly, it is desirable to provide an improved process forproducing a colorant for keratin fibers. In addition, other objects,desirable features and characteristics will become apparent from thesubsequent summary and detailed description, and the appended claims,taken in conjunction with the accompanying drawings and this background.

SUMMARY

A method for manufacturing a coloring agent for keratin fibers isprovided. The method includes directing a composition A from a containerA by a filler apparatus through an inlet opening into a container Bcontaining a composition B. The coloring agent for keratin fibers exitsfrom the container B as a mixture of the composition A and thecomposition B. The composition B contains a fatty alcohol, analkoxylated fatty alcohol, and a fatty acid.

DETAILED DESCRIPTION

It has now been found that the aforementioned disadvantages ofconventional mixing methods can be eliminated by a method formanufacturing a coloring agent for keratin fibers, in accordance with anexemplary embodiment, from a composition A and a composition B, in whichmethod:

-   -   the composition A is directed from a container A    -   by a filler apparatus    -   through an inlet opening    -   into a container B containing the composition B, and the        coloring agent for keratin fibers exits from the container B as        a mixture of compositions A and B,        wherein the composition B encompasses

a) a fatty alcohol, as well as

b) an alkoxylated fatty alcohol, and

c) a fatty acid.

In the context of the method according to an embodiment, twocompositions A and B differing from one another are mixed with oneanother, forming a coloring agent for keratin fibers.

Composition A is introduced from a container A. This container A isconfigured in an embodiment as a storage container, and encompassesseveral times the quantity of composition A needed for carrying out asingle mixing method. In other words, in an embodiment, a sub-quantity aof composition A present in container A is introduced into container B,a residual quantity of composition A present in container A remaining incontainer A until the end of the mixing method, and that residualquantity corresponding to twice, for example at least four times, and inparticular at least eight times the quantity of sub-quantity a.

In a further embodiment, container A comprises two or more chambers(e.g.: A1 and A2) in which compositions (e.g. A1 and A2) differing fromone another are present separately from one another. The apparatus usedto carry out the method is embodied in such a way that the user selectsbetween the two or more chambers or alternatively uses, for example, acomposition A1 in a first mixing method and a composition A2 in thesubsequent mixing method.

Alternatively to the above-described multi-chamber configuration ofcontainer A, the apparatus for carrying out the method according to anembodiment also provides two or more separate containers for thereception of different compositions A.

In an embodiment, the introduction of composition A from container Ainto container B is accomplished by a directing system attaching tocontainer A. Located at the end of this directing system is the fillerapparatus provided for introducing composition A into container B. Toshorten the duration of the method and to improve the method's results,in particular the intermixing quality, composition A is introduced intocontainer B for example at a pressure above about 1.1 bar, for exampleabove about 2.0 bar, for example above about 5.0 bar, such as in therange of from about 10 to about 20 bar.

Composition A is introduced in the course of the method into containerB, out of which the coloring agent for keratin fibers then exits fromcontainer B as a mixture of compositions A and B.

In an embodiment, container B used for this is fastened by an adhesive,latching, snap-on, or clamping mechanism in the apparatus used to carryout the method.

Container B, in an embodiment, is embodied in the form of a sealedcapsule. This sealed capsule is opened by the directing system conveyingcomposition A. The opening operation occurs by penetration of thecontainer wall of container B, for example by the filler apparatuslocated at the end of the directing system. This filler apparatus can beembodied, for example, in the form of a spike. Once the container wallhas been punched through, composition A is then introduced intocontainer B.

In another embodiment, at least one exit opening is formed in containerB as a result of the introduction of composition A. The reason for theformation of the exit opening can be, for example, the increasingpressure in container B. Alternatively, however, the exit opening canalso be formed by the action of the filler apparatus, for example by thefact that the filler apparatus pushes through the container wall ofcontainer B at two points, or by the fact that the pressure occurring inthe container as a result of penetration of a container wall causesformation of the exit opening.

Methods contemplated herein in which container B is formed by theintroduction of composition A, and/or the action of the filler apparatusforms at least one exit opening from which the coloring agent forkeratin fibers exits from container B as a mixture of compositions A andB, make possible simple and effective mixing of the compositions beingused.

The formation of the exit opening in the container wall of container B,in particular the exact location at which said exit opening is formed,is controlled by the specific construction of container B, in anexemplary embodiment.

In a first embodiment, container B possesses a weakening line alongwhich the exit opening is formed as a result of the introduction ofcomposition A and/or the action of the filler apparatus.

In a second embodiment, the container possesses a membrane that ispressed against a spike, accompanied by formation of the exit opening,as a result of the introduction of composition A and/or the action ofthe filler apparatus. The membrane is a constituent of the containerwall of container B. The exit opening is generated by the penetration ofthe membrane by the spike. The spike can be arranged both insidecontainer B and outside container B. In the case of a spike arrangedinside container B, the container wall of container B is opened from theinside outward. If the spike is located outside container B, the spikepushes the container wall from the outside inward. In an embodiment, thecontainer wall of container B comprises, in the area of action of thespike, a weakening line by which, for example, the size of the exitopening can be influenced.

In a further embodiment, to improve the mixing effect, composition Aand/or the mixture of compositions A and B passes through a static mixerin the course of the method. This static mixer can be arranged, forexample, inside the above-described directing system, but is preferablylocated in the immediate vicinity of the exit opening of container B,for example inside container B or outside the exit opening. In thelatter case the static mixer can be embodied as an integral constituentof container B. Alternatively, the static mixer is a constituent of theapparatus used to carry out the method, and is associated, for example,with the adhesive, latching, snap-on, or clamping mechanism used tofasten container B.

Particularly homogeneous mixing of the compositions being used isachieved due to the arrangement of a static mixer inside container B,and methods contemplated herein in which container B comprises a staticmixing element in its interior are therefore suitably used.

Composition B present in container B is discharged in the course of themethod by the introduced composition A, out of container B through theexit opening. Discharge occurs, in an embodiment, substantiallycompletely. In other words, at least about 80 wt. %, for example atleast about 90 wt. %, for example at least about 95 wt. %, such as atleast about 98 wt. % of composition B is discharged from the container.

In an embodiment, the volume ratio of compositions A and B used in themixing method is from about 10:1 to 1:1, such as about 6:1 to about 2:1.The absolute volume of composition A used is for example in the range offrom about 5 to about 500 ml, for example from about 10 to about 400 ml,such as from about 20 to about 300 ml.

In another embodiment, the weight ratio of compositions A and B used inthe method is in the range of from about 1:1 to about 20:1, for examplefrom about 2:1 to about 10:1, such as from about 3:1 to about 8:1.

In an embodiment, compositions A and B are not heated by an externalheat source in the course of the mixing method. The temperature ofcomposition A may be less than about 35° C., for example less than about30° C., such as less than about 25° C. The temperature of the coloringagent for keratin fibers upon exiting from container B likewise may befor example less than about 35° C., for example less than about 30° C.,such as less than about 25° C.

In another embodiment, the coloring agent for keratin fibers that isobtained as the end product of the method has a pH in the range of fromabout 5 to about 12, such as from about 7.5 to about 11.

The method contemplated herein is suitable for manufacturing coloringagents for keratin fibers having a viscosity above about 20,000 mPas(Brookfield viscosimeter, spindle 5, 4 rpm), for example in the range offrom about 20,000 to about 100,000 mPas (Brookfield viscosimeter,spindle 5, 4 rpm), such as from about 25,000 to about 40,000 mPas(Brookfield viscosimeter, spindle 5, 4 rpm).

In an exemplary embodiment, to adjust the viscosity of composition B andof the coloring agent for keratin fibers, and to achieve sufficienthomogeneity for the coloring agent for keratin fibers, composition Bcontains a fatty alcohol in combination with an alkoxylated fattyalcohol and a fatty acid.

In an embodiment, the use of fatty alcohol a) from the group of C₈ toC₂₂ fatty alcohols, for example from the group of C₁₀ to C₂₀ fattyalcohols, and in particular from the group of C₁₂ to C₁₈ fatty alcoholshas proven particularly suitable in terms of the viscosity andhomogeneity of the coloring agent for keratin fibers that is obtained.The weight proportion of the fatty alcohol in terms of the total weightof composition B is for example from about 0.1 to about 10 wt. %, forexample from about 0.15 to about 8.0 wt. %, such as from about 0.2 toabout 6.0 wt. %.

Fatty alcohols a) are combined, according to an embodiment, with analkoxylated fatty alcohol b). The use of alkoxylated fatty alcohol b)from the group of ethoxylated fatty alcohols, for example from the groupof ethoxylated C₈ to C₁₆ fatty alcohols, such as from the group ofethoxylated C₈ to C₁₄ fatty alcohols has proven particularly suitable interms of the viscosity and homogeneity of the coloring agent for keratinfibers that is obtained. The weight proportion of the alkoxylated fattyalcohol in terms of the total weight of composition B is for examplefrom about 0.1 to about 40 wt. %, for example from about 1.0 to about 30wt. %, such as from about 2.0 to about 20 wt. %.

The fatty alcohols a) and alkoxylated fatty alcohols b) are furthercombined according an embodiment with a fatty acid c). The use of fattyacid c) from the group of C₈ to C₂₄ fatty acids, for example from thegroup of C₁₂ to C₂₂ fatty acids, such as from the group of C₁₄ to C₂₀fatty acids has proven particularly suitable in terms of the viscosityand homogeneity of the coloring agent for keratin fibers that isobtained. The weight proportion of the fatty acid in terms of the totalweight of composition B is for example from about 1.0 to about 20 wt. %,for example from about 2.0 to about 18 wt. %, such as from about 5.0 toabout 15 wt. %.

The viscosity properties of composition B with respect to the coloringagent for keratin fibers that is obtained by mixing compositions A andB, and the homogeneity properties of the mixture, can be furtherimproved by the addition of oil components or alkoxylated fatty alcoholsulfates.

Accordingly, in an embodiment, composition B contains an oil componenthaving a melting point below about 25° C. from the group of theparaffins. The weight proportion of the oil component in terms of thetotal weight of composition B is for example from about 0.1 to about 50wt. %, for example from about 1.0 to about 40 wt. %, such as from about5.0 to about 30 wt. %.

In another embodiment, composition A and/or composition B contains analkoxylated fatty alcohol sulfate, for example an ethoxylated C₈ to C₁₆fatty alcohol sulfate, for example an ethoxylated C₈ to C₁₄ fattyalcohol sulfate. The weight proportion of the alkoxylated fatty alcoholsulfate in terms of the total weight of composition A and/or ofcomposition B is for example from about 0.05 to about 30 wt. %, forexample from about 0.1 to about 10 wt. %, such as from about 1.0 toabout 5.0 wt. %.

The use of a polymeric thickening agent, in a further embodiment, issuitable for further improvement of the homogeneity and viscosity of thecoloring agent for keratin fibers manufactured by the methodcontemplated herein. The thickening agent is for example added tocomposition A. From the extensive group of polymeric thickening agents,the use of polymeric thickening agents from the group of acrylic-acid ormethacrylic-acid copolymers has proven particularly suitable for themanufacture of a coloring agent for keratin fibers having sufficientviscosity along with satisfactory homogeneity. A polymer that isparticularly suitable is the copolymer known by the INCI name AcrylatesCopolymer, made up of two or more monomers selected from acrylic acid,methacrylic acid, and esters thereof with C₁ to C₆ alkyl groups. Inorder to achieve advantageous viscosity and homogeneity values, theweight proportion of the polymeric thickener in terms of the totalweight of composition A is for example from about 0.01 to about 50 wt.%, for example from about 0.1 to about 30 wt. %, such as from about 0.5to about 20 wt. %.

Compositions A and B that are mixed with one another in the method canfurther contain, besides the obligatory constituents recited above, aplurality of hair-color-changing active substances. For example,

two different oxidation dye precursors,

two different substantive dyes,

two oxidizing agents of different strength,

an oxidizing agent and an oxidation dye precursor,

an oxidizing agent and a substantive dye, or

an oxidation dye precursor and a substantive dye can be mixed in themethod to yield a coloring agent for keratin fibers.

In another embodiment, composition A contains an oxidizing agent and/orcomposition B contains a coloring agent from the group of oxidation dyeprecursors and substantive dyes.

In a further embodiment, composition A is flowable and is present in theform of a liquid, a gel, or a paste. Suitable liquid compositions Acontain for example at least about 30 wt. %, for example at least about40 wt. %, such as at least about 50 wt. % water. The weight proportionof water is for example in the range of from about 30 to about 98 wt. %,for example from about 40 to about 96 wt. %, such as from about 50 toabout 94 wt. %, based in each case on the total weight of composition A.

In a variant of the method, composition A contains an oxidizing agent,for example from about 0.5 to about 50 wt. %, for example from about 1.0to about 20 wt. %, for example from about 2.5 to about 16 wt. %, such asfrom about 5.0 to about 14 wt. % hydrogen peroxide (calculated as 100%H₂O₂), based in each case on the total weight of composition A.

Composition B can be present in flowable form, for example as a liquid,gel, or paste, but also as a solid, in particular as a powder orcompressed powder. In terms of the duration of the method and in orderto improve the method's results, in particular the mixing quality,however, flowable compositions B have proven advantageous as comparedwith solid ones.

Correspondingagents therefore of course contain suitable coloring or decolorizingactive substances. In this regard, composition B contains an oxidationdye precursor or a substantive dye.
